Maintenance of E Type Spherical Roller Bearings

Wuxi Spark Bearing Co.,Ltd mainly deal with spherical roller bearings,today we share some information for E type spherical roller bearings  

E type spherical roller bearings can bear multi-direction force, high rotating speed and large bearing capacity.Symmetrical spherical roller, two quenched steel punch cage, inner ring without retaining edge and a center retainer guided by cage.The middle retainer near the outer ring can improve the lubrication between the end face of the roller and the retainer ring. Its function is to reduce bearing friction, help guide the roller in the non-load zone, and assist the roller to enter the load zone. At the same time, the length of the roller increases, so the rated load has been greatly improved.Usually the rated load can be increased by 20%~35%.

Contact fatigue and wear resistance, flexibility are directly affected by long life.In order to meet the quality requirements of batch, efficiency and quality, the dynamic bearing has good performance.For example, cold and hot forming performance, cutting performance, hardenability, and so on.Bearing in the working state hardness between HRC61~65, so that the bearing to obtain higher contact fatigue strength and wear resistance.In order to prevent the bearing parts and finished products from being corroded and rusted in the process of storage and use, it is required that the bearing should have good anti-rust performance.Need WSBC 22212 E,click here to learn more.

The optimized lubrication system can reduce the internal friction and damage of bearings, effectively prevent and avoid friction heating, burn, damage and adhesion, and improve the working life of bearings.Cooling friction heat, cooling, prevent bearing heating, eliminate lubricating oil aging;It also solves the problem of foreign matter intruding into the bearing, rust and corrosion.During the normal operation of the bearing, rolling friction and sliding friction will occur in the ring, rolling (ball = cylinder) and cage, and the parts of the bearing will work and wear.It can reduce the wear of bearing parts, maintain the stability of bearing precision, extend the service life, and increase the wear resistance of bearing.

Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear, and the oil film also plays a fixed vibration absorbing capacity. The sharp squeaking noise may be caused by improper lubrication.Improper bearing clearance can also cause metallic sound.If there are pollutants in the bearing will often cause hiss, serious bearing damage will produce irregular and loud noise.Bearing damage can be detected by listening, but usually at this time has reached the need to replace the bearing is not.Therefore, better methods such as using electronic condition monitoring instruments.

The bearing and bearing housing ring shall be inspected, and the bearing shall be replaced if cracks, fatigue spalling and loose roller are found.Bearings should also be replaced if pitting is found on the bearing ring.Click here to learn more about WSBC 22310 E
